The Guide: Altimeter, Barometer, Compass, is a premium, multi-sensor digital movement surrounded by a 48mm 316L surgical-grade stainless steel case and an ultra, scratch-resistant K1 crystal. The movement features an instant Altitude read out along with an elevation-gain graph. The Barometer is ready to alert you if your summit attempt is a poor decision with the storm warning indicator. The digital compass, when paired with the bi-directional rotating bezel, will hold your bearing for quick reference. The custom strap is 22mm wide polyurethane featuring the patent-pending, modified OKTOLOCK system and a 316L surgical-grade, stainless steel buckle. All case, strap and buckle connection points utilize screw-down, stainless steel parts for added durability. Finally the 10 ATM water resistance means the Guide can withstand the elemental forces that can occur during river crossings or high-alpine thunderstorms while also providing a temperature reading both in and out of the water.
